CCHDO Hydrographic Data Archive

CCHDO contains hydrographic data collected from research vessels globally. Data are aggregated from science party submissions from programs such as GO-SHIP, WOCE, and CLIVAR aimed at reference-quality data. The data are assembled by cruise into several standard formats (e.g. WHP-Exchange, WOCE, and netCDF), as well as assessed for consistent parameter naming and flags, and known units of measurement. Data are not further quality controlled by CCHDO. The primary location of the CCHDO dataset is https://cchdo.ucsd.edu/. Snapshots of the CCHDO data and metadata are being deposited periodically for long-term preservation and access at the UC San Diego Library and are therefore also available through this collection. The most recent snapshot can be accessed at the top of the list of collection items.
